SERP Comments:

While validated as an inhibitor of BCL6 for use in cells (at 1 µM), chemically induced BCL6 degraders have stronger effects than BCL6 inhibition using this compound.

SERP Comments:

This is a potentially very interesting molecule, but its putative and relatively complex mechanism of action (binder/degrader whose activity depends also on other domains not directly targeted) makes it still not ideal as bona fide validated chemical probe. The authors also do not recommend using this probe in vivo (10.1016/j.celrep.2017.08.081, albeit only a limited oral PK was performed). Investigators are recommended to carefully read the original manuscripts reported above prior to use this agent and carefully evaluate and interpret their results in the context of these previous findings.
